Proposed JPL tidal power system Rather than creating the electricity underwater then send it to land on expensive, easily corroded underwater cables, this new tidal power system from NASA “uses water motion to generate a high-pressure liquid rather than electricity. That liquid is then transported to shore and used to produce electricity on land.” [...] Atlantis Resources tidal turbine Atlantis Resources of Singapore has tidal power projects planned in Scotland and Australia. The Scotland project could eventually output 1GW, as much as a large coal plant, of clean, renewable energy. Huge data centers housing tens of thousands of computers may be built there, with the electricity coming from tidal [...] Video: Ocean Renewable Power successfully tested a submerged turbine during one of the roughest winters in decades in Maine A nearly $1 million federal grant to UMaine and Ocean Renewable Power will be used to determine if submerged turbines can reliably create power from tidal currents in estuaries. Maine has huge potential for tidal [...] One day, marine power like this will be commonplace. May it happen soon. This short animation from Greenpeace explains the basics. Electricity can be generated when the tide is coming out or in. Plus, unlike wind or solar, tides are steady, you know exactly when the power will be generated. The UK is studying the feasibility of a massive tidal power project at the Severin Estuary and have all the info online. Nice. The Saltire Prize of £10 million will go to the company with the best plan for tidal or wave energy in the waters of Scotland, which is already a leader in such energy. The Scottish government said the potential wave and tidal capacity in its waters is estimated at 21.5 GW, with studies showing [...] This SeaGen tidal power turbine recently output 1.2 megawatts, generating at full power. This is way more than any other tidal turbine done. Artist’s conception of a wave farm of 750-kW Pelamis wave converters. Chemical and Engineering news has an excellent overview of the various technologies being developed to create electricity from moving water. The primary methods are wave and tidal. Wave Waves are powered by winds and uneven solar heating, he says, and wave energy works [...] ScottishPower Renewables plans to build tidal turbine farms in the Pentland Firth area of the Orkneys, which has been called “the Saudi Arabia of marine energy” because of its powerful tides. The tidal farms could provide power for as many as 40,000 homes. [...] |  | ||||
